Hemoencephalography (HEG)

Hemoencephalography biofeedback (HEG) is a different form of biofeedback to brainwave neurofeedback. HEG training feeds back changes in the brain’s energy consumption (which is related to blood flow, oxygen, nutrient, glucose supply). HEG training aims to boost blood flow activity to your brain and as a result it improves mental and emotional functioning. There are two types of mainstream HEG sensors, either a sophisticated infrared thermometer known as a passive infrared HEG (pirHEG) or, a near infrared HEG (nirHEG) sensor that shines light through the skin and skull to assess the colour of brain tissue. Oxygenated arterial blood is red, deoxygenated venous blood is blue. Increased demand for nutrition results in faster blood flow and redder blood in the tissues leads to more effective function.
